SHADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 242,592, dated June '7,18 81.

Application filed April 30, 1881. (No model.)

To all whom it may concern:

Be it known that I, NATHANIEL L. BRAD- LEY, of Meriden, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inShade-Holders; and Ido hereby declare the following, when taken inconnection with the accompanying drawings, and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,

10 and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a vertical central section; Fig. 2, plan of the holder fromthe inner side.

This invention relates to an improvement in the method of securinglamp-shades to the shade-ring. In the usual construction this is done bymeans of screws or rigid holders confining the shade rigidly to theholder.

The object of this invention is to produce a yielding holder, and which,if the shade be thrown out of place, will automatically return it to itsproper position; and it consists in the construction, as hereinafterdescribed, and particularly recited in the claim.

In the Patent granted to me June 8, 1880, N 0. 228,594, two or moresprings were attached by one end to the shade-ring at different points,the other end of the spring engaged with the opposite edge of the shade,and so that the 0 power ofthe springs holds the shade to its seat on theshade-ring, as these springs are the only means for holding the shade,and several springs are necessary.

In this invention the object is to use but a single spring applied atone point, while stationary hooks or lugs on the shade-ring at otherpoints will perform the office of the other springs, and generally makethe holding of the shade permanent.

In the illustration the invention is shown as applied to that class ofshades which are of inverted funnel-shape, and attached to the ring atthe top.

A represents the ring, and B the shade, which maybe of any of the usualshapes. The 5 ring is constructed at one side with a lug, a, which willpass within the shade, and at each side of this lug is another lug, b,arranged to pass beneath the flange of the shade, as indicated in brokenlines, Fig. 1. Upon the opposite side a spiral or other suitable spring,C, is attached, by one end, (I, to the shade-ring, preferably inside theshade, and the other end provided with a hook, e, to engage theopposite, or, in that case lower, edge of the shade. 5 5 The shade isintroduced by first engaging the edge with the lugs a b on one side,then bringing it to its seat in the ring, when the spring may beapplied, as shown, to hold it in that position. The spring will yield,so that by no possibility can the shade be bound in its seat, as by'ascrew, to cause it to break.

The particularconstruction of thelugs Which combine with the spring tohold the shade is not material, it only being essential that a rigidengagement be made between the shade and the shade-ring opposite to thespring.

It will be understood that this fastening device may be applied in likemanner to other shapes of shades or globes.

I claim- The combination of the shade-supporting ring and shade with arigid device on one side to engage the flange of the shade, and thespring C upon the opposite side, attached by one end to the shade-ring,the other end eugaged with the opposite edge of the shade, allsubstantially as described.
